There is no tabular data in the model building codes suitable for Post Frame <br /> constniction(isolated shallow posts). <br /> RAM Buildings and the engineer acknowledge that acceptance of this analysis for any perticular project is up to the <br /> discretion ofthe Building Ofticial. Halberg Engineering specializes in Post Frame Engineering and Aaron Halberg <br /> has develop�this information based on latest industry information and the current building codes and standards. <br /> This analysis is deemed snitable for buiiding sitcs where it is reasonable to presume safe soil bearing pressure is at <br /> least 2,500 Ibs per sq.ft.(ps� <br /> Conditions and/or assumptions in this analysis: <br /> Base soit pressure presumed to be 2,SOOpsf <br /> Ram Buildings typical post frame building loads apply: . <br /> D 35psf Top Chord Live Load <br /> D +Spsf Top Chord Dead Load <br /> ➢ +�nsf Bottom Chord Dead Load <br /> ➢ = 45a�fTntsll.n�d <br /> ➢ 6 feet or 8 feet spacing between sidewall columns,with cicar span ttuss spacing matching the c:olumn spacing. <br /> D 4 feet post embedment depth from Top of Finished Floor to Top of Footing(see diagram) <br /> Pre-cast Plain Concrete footings(f,'���y�=4,000 psi). <br /> Optiona!use of Dry Mix at the base of the hole supporting a precast concrete footing is presented as an option to maximize <br /> tho allowable load for a given post hole size with minimum sVength required of the dry mix itself. Use of the Dry Mix is <br /> based on successful industry experience and technical research documented in ASABE paper#034003 titled"In-Situ • <br /> _Hydration of a Dry Con�ret�1Gtix". <br /> RAM Maxtmum Span for each footin Column/Truss s acin <br /> Concrete Footin Solution: 6 feet 8 feet <br /> 16"�x 4"Precast 40' 44' 29' 33'y <br /> 16"�x 4"Precast on 40f►of Dry Mix(18"�hole 54'(58') 4tY(44'j; <br /> 20"�x 6"Precast 70'(74' S1'{55') <br /> 20"�x 6"Precast on 120#of Dry Mix(24"{6 hole) 106'(110') 78'(82') <br /> The maximum clear span building is shown for each footing condition assuming a 2'building overhang.
